The Central Texas Clean Air Coalition (CAC) is a voluntary association of organizations that support the regional effort toward improvement of air quality in the Austin-Round Rock Metropolitan Statistical Area (MSA), which consists of Bastrop, Caldwell, Hays, Travis, and Williamson Counties. The purpose of the CAC is to:

• Develop, adopt, and implement clean-air plans to achieve and maintain compliance with federal ground-level ozone standards
• Establish and monitor a regional effort toward the improvement of air quality
• Develop policies and strategies that will provide guidance for each of its independent governing bodies about actions that will achieve clean air in Central Texas
• Work cooperatively to achieve clean air standards that will protect public health while allowing organizations to select measures best suited to each community's and organization's needs and resources

The CAC includes both "General Members" and "Supporting Members." General members include city and county governments that have made specific commitments to implement measures in support of the region's air quality plan and appoint an elected official to serve as a voting representative at CAC meetings. Supporting members include any organization that takes action to support the purpose of the CAC and reports their actions periodically to the CAC.

The CAC has an advisory committee that consists of staff members from each CAC member organization.
